The memmove implementation relies on the variable runtime.arm64UseAlignedLoads to select fastest code path. Considering Neoverse N2 and V2 cores prefer aligned loads, this patch adds code to detect them for memmove performance. And this patch uses a new variable ARM64.IsNeoverse to represent all Neoverse cores, removing the more specific versions.
